Sand 3D printing technology empowers automotive manufacturing upgrade

In the field of automotive manufacturing, sand 3D printing technology is playing an increasingly important role: 1. Enhance the freedom of design and innovation efficiency, rapid manufacturing of engines, chassis parts and other design prototypes, accelerate the verification and optimization, shorten the R & D cycle; 2. Tackle the complex and precision parts manufacturing challenges, such as pump body, closed impeller and other traditional processes difficult to process parts, eliminating the restrictions on the release of the mold, improve the performance of the parts; 3. Achieve efficient and flexible small batch customization without the need for expensive molds; 4. Flexible small batch customization, without expensive molds, rapid response to market demand; 4. Protect the quality of core parts casting, direct printing of high-precision functional sand core (such as the internal structure of the engine block), to ensure the quality of castings.

With its mature sand 3D printing technology, SANDI has provided solutions for many domestic and foreign automobile enterprises covering motor shells, lightweight frames, shells, cylinder blocks/cylinder heads, exhaust pipes and other serialized products, and has especially accumulated rich experience in the manufacturing of automobile powertrain, transmission parts and precision structural parts.

Strong combination, common molding industry benchmarks

FAW Casting, as a leading enterprise in China's automobile manufacturing industry, has long been committed to the research, development and production of high-quality automobile parts and engineering machinery castings, and actively promote the transformation of intelligent manufacturing. The main body of this project, FAW Casting Wuxi Branch, focuses on the development and production of core castings for medium and heavy truck engines (such as cylinder blocks, cylinder heads, crankshafts, flywheels, etc.), and is in a leading position in the field of thin-walled high-strength cast iron production technology in China. The two sides have a long history of cooperation, as early as 2008, FAW Casting has introduced the SLS laser sand printing equipment of Longyuan Molding, a subsidiary of SANDY Technology, for the rapid trial production of complex products such as engine blocks and cylinder heads.

The project manager of SANDI Technology said, "The winning of the bid is a full affirmation of SANDI Technology's 3D casting technology strength and service capability. We will make every effort to ensure the smooth implementation of the project, help FAW Casting to enhance the speed of new product development, improve product quality and production efficiency, and jointly make the project an industry application model of 3D printing digital production in the field of automobile manufacturing."

With the development of the automobile industry in the direction of intelligence, lightweight and customization, 3D printing technology is deeply integrated into the whole life cycle of automobile manufacturing from conceptual design, R&D trial production to manufacturing and maintenance services. The cooperation between SANDI and FAW Casting will further promote the large-scale application of 3D printing technology in the field of automotive core parts manufacturing, and inject new kinetic energy for the industry's high-quality development.
